Sweeping machine and visual control method, controller and control system for suction nozzle of sweeping machine

Abstract

The invention discloses a visual control method for a suction nozzle of a sweeping machine. The visual control method for the suction nozzle of the sweeping machine is characterized by comprising the following steps: a camera device is used for shooting an image of a road surface in front of the sweeping machine, and a condition of rubbish of the image is judged to accordingly adjust the size of a suction inlet of the suction nozzle. The invention further provides a visual controller and a control system for the suction nozzle of the sweeping machine. Through the technical scheme, the camera device is used for monitoring the road surface in front of the sweeping machine to accordingly adjust the suction nozzle according to monitoring information of the rubbish condition in the image, so that the size of the suction inlet is adjusted reasonably, the rubbish suction capacity of the suction nozzle is improved, and the sweeping machine is enabled to response to different road conditions to achieve good a sweeping effect.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a control method, a controller, a control system and a road sweeper including the control system for the visualization of the suction nozzle of the road sweeper. Background technique [0002] In the existing road sweeper, a suction nozzle is usually used to suck the garbage, and the suction nozzle is connected with a suction pipe, and the garbage on the road surface is sucked into the garbage hopper of the road sweeper through the suction nozzle by the negative pressure in the suction pipe. [0003] When the road sweeper performs cleaning operations, under the action of the fan, a negative pressure is formed in the suction nozzle, and the garbage on the road surface is sucked from the suction port under the negative pressure of the suction pipe, and then enters the garbage hopper through the pipe. The suction nozzle of the current road sweeper usually includes a rubbe...

AI Technical Summary

Problems solved by technology

The suction nozzle of the current road sweeper usually includes a rubber baffle, which can elastically deform under the negative pressure formed by the fan to increase the suction port of the suction nozzle, but the position of the rubber baffle can only be It is manually disassembled and assembled before operation, and the position is fixed during operation, so it is difficult to adjust the suction nozzle reasonably according to the change of working conditions, especially when there are hard and large garbage on the road surface, it is easy to cause garbage dragging and blockage, etc. The phenomenon affects the garbage suction capacity of the suction nozzle, and at this time the operator has to leave the cab to adjust the suction nozzle before continuing to work, which brings a lot of inconvenience
